Definitions
- the present invention relates to an assembly formed of a tire without an inner tube, intended to be mounted on a rim, and of a device intended to ensure the seal between said rim and said tire. It relates more particularly to assemblies for heavy vehicles.
- Patent FR 1 130 534 shows such an assembly with a tire internally comprising a layer impermeable to the inflation gases generally used.
- the service rim of said tire is a rim comprising seats slightly inclined relative to the axis of rotation (flat seats or seats inclined at an angle equal to 5 °). It comprises on each side of the rim tape a fixed rim and a removable rim, locked by any suitable means, in particular by a split locking ring which is received in a groove provided for this purpose.
- On the side of the fixed rim whether the rim seat is flat or inclined at 5 °, the bead of the tire is housed on said seat and against the rim: this results in a certain seal.
- the rim is not waterproof, hence the need, to mount and allow the correct rolling of the tire without an inner tube, to install a sealing part made of material.
- elastomeric, part which can be in the form of two edges having in meridian section the form of angles, said two edges being joined axially by a quasi-flat strip on which is disposed in an airtight manner an inflation valve.
- This sealing part gives the assembled assembly the necessary sealing if the dimensioning, in particular the thicknesses between the beads and the insulating seats are sufficient, at least over a substantial axial part.
- the invention proposes to ensure that the two edges of the sealing piece made of elastomeric material are integral with the tire, thus making it possible to reassemble said tire after having removed the latter from its service rim.
- the assembly according to the invention comprises a tire without an inner tube, provided with two beads and intended to be mounted on a rim comprising seats extended radially outwardly by flanges, and a rubbery sealing piece disposed between said rim and said tire; this tire has diameters DP of bead seats greater than the corresponding diameters DJ of the mounting rim seats; in addition, this tire is integrally provided with a sealing part formed by three parts integral with each other, a central part, made of a rubber mixture impermeable to inflation gases and placed axially between the beads of the tire, this central part extending axially at least under the beads of the tire by two parts forming edges of material resistant to compression (and not necessarily impermeable to inflation gases), these edges being integral with the beads of the tire and separable from the central part.
- the sealing part comprises means having the function of allowing a localization of the separation zone between the edges and the central part of said part in order to 'facilitate this separation by means of a cutting tool in particular by avoiding
- these locating means take the form of a groove (or rib) oriented in the circumferential direction and produced on the face of the sealing piece intended to face the rim tape surface; this groove (or rib) has a suitable depth (or thickness) so as not to weaken the connection between the central part and the edges of the sealing part in new condition.
- This groove (rib) serves, when removing the central part, as a guide for a cutting tool to cut the sealing piece between the central part and the edges in order to avoid injuring the bead of the tire while by making a satisfactory cut from the first separation attempt.
- this part is produced by gluing between the central part and the edges according to a preferably oblique plane at an angle ⁇ at most equal to 60 ° (angle measured relative to the axial direction); this bonding zone can be materialized by the presence of a material of a color different from the color of the sealing part.
- the edges are, seen in meridian section, in the form of strips of rubber mixture resistant to impact and breakage which can be caused by the assembly and disassembly tools of the assembly on its rim.
- the average thickness of each edge is such that the difference between the average diameter of the rim seat and the average diameter measured on the part of the assembly intended to come into contact on said seat is between 0 and 4 mm.
- tightening is meant the value of the compression deformation of the materials present in the assembly under a rigid annular element to which a carcass reinforcement is anchored during mounting on the service rim. This tightening is defined by the following relationship:
- DJ is the diameter of the rim measured on a perpendicular to the axis of rotation of the assembly passing through the center of gravity of the meridian section of the bead reinforcement rod
- DT is the diameter of the base of the rod taken on the same perpendicular
- DB is the inside diameter of the assembly (tire - sealing piece) taken on the same perpendicular.
- Said tightening can be constant axially along the rim seat; it can also vary, as known per se, due to the possible differences between the rim seats and the seats of the beads provided with the sealing parts.
- the tightening can increase by going from the edges to the point of the beads; but it can just as easily decrease.
- Said tightening variations can be made by varying the thickness of the edges of the sealing part, or by varying the profile of the tire seat without said part.
- the edges are, seen in meridian section, in the form of bands with curved edges in a rubber mixture resistant to impact and breakage which can be caused by the assembly and disassembly tools of the assembly on its rim, each part curved. extending radially outward the portion of the edge located radially under each bead; these curved parts can advantageously be made of a material resistant to wear by friction against the flanged edges.
- the sealing part can be made with an identical material for the central part and the edges, it being understood that this material must at least have sufficient airtightness characteristics and be able to be made integral with the beads of the tire.
- the material constituting the sealing part can be any material having sufficient flexibility as well as air tightness allowing both mounting and inflation (and not necessarily in a rubber mixture).
- the permeability of the material of the central part is measured by a coefficient of permeability c, measured at 80 ° C according to DIN standard n ° 53 536 and is expressed in m 2 / s. Pa. This coefficient will preferably be less than 7 10 ⁇ ⁇ m 2 / s. Pa.
- the fixing of the sealing part to the beads of a tire to form a closed pneumatic assembly can, for example, be carried out by bonding using a bonding material ensuring both bonding on the bead and on the edge. of said piece.
- the central part of the sealing part is removed, leaving the edges of this part in place under the beads of said tire; this is possible because the sealing part was integral with the tire by its two edges. In this way the tire provided with these edges can again be easily mounted on the same service rim with an air chamber.
- the pneumatic - sealing part made of rubber mixture forms a whole and its manufacturing process comprises the following stages: a) manufacture and vulcanization of a tire with incorporated chamber, as known per se, the diameters of the tire bead seats being at least equal to the diameters of the corresponding service rim seats, b) manufacture of a sealing part not vulcanized in a rubber mixture by co-extrusion using for example a roller nose extruder, this part comprising axial end parts forming edges, c) fitting of the sealing part to the interior of the tire so that the beads of this tire are in abutment on the edges and positioning of this assembly on an assembly drum having a radially expandable cylindrical molding surface, this surface being limited axially by lateral parts axially limiting the axial displacement of the beads in the next step; d) radial expansion of the assembly drum and inflation of the tire to a sufficient pressure to obtain an appropriate contact between the sealing part and the beads of the tire, e) vulcanization of the sealing part to make said part integral
- the edges of the sealing part have curved parts, it is advisable to provide that the lateral parts limiting the axial movement of the assembly on the assembly drum have a meridian profile similar to the meridian profile of the service rim .
- FIG. 1 partially represents a section of a assembly formed by a tire, a sealing part and a rim
- FIG. 2 is a view of the same assembly after removal of the central part of the sealing part
- Figure 3 shows another variant of an assembly according to the invention mounted on a service rim.
- the assembly not mounted on its rim, in accordance with the invention, and shown partially in FIG. 1, is composed of a tire P without independent inner tube and of a sealing part E to be mounted on a rim service J shown in dotted lines.
- the tire P has a usual structure and mainly comprises a metal carcass reinforcement 1, radial in the case studied and anchored in each bead to at least one bead wire 2 to form a reversal 10.
- the bead has a wall formed:
- Said part is composed of three parts: two lateral parts 50 having the shape of frustoconical crowns intended to be disposed, in an integral manner, between the bead seat 42 and the rim seat 440.
- the thickness e 0 of the edges of the sealing piece E is measured on a perpendicular to the axis of rotation passing through the center of gravity of the anchor rod 2 and is equal to the difference (DP - DB), DP being the diameter on said perpendicular of the bead of the tire P and DB being the inside diameter of the crown 50 of the sealing piece E.
- This thickness e 0 is determined by so that there is an appropriate tightening of the assembly (tire - sealing part) on the rim J between the bead wire 2 and said rim.
- a central part 51 which may have a thickness e t greater than the thickness e of the lateral parts 50, and which is provided with an orifice necessary for fitting a valve base.
- a groove 52 extending circumferentially on the radially inner face 53 of the sealing part E and on only part of the thickness of the sealing piece.
- This groove is positioned substantially between the central part 51 and one of the lateral parts 50 of the sealing part and has the function of allowing a correctly localized and easy cutting of the central part without creating damage to the beads.
- This groove 52 serves both as a guide for positioning the cutting tool and as a guide for this tool for separating the central part 51 from the lateral parts 50.
- the tire assembly - sealing part in new condition, unassembled and not inflated and in the same figure a section of the mounting rim J in dotted lines comprising a seat frustoconical surface rim 440 extended axially and radially outside by a flange R; according to this representation, it is easy to understand the tightening of the materials of the tire and of the sealing part under the bead wire 2 in the beads when the assembly according to the invention is mounted on this rim.
- the rubber mixture constituting the lateral parts 50 of the part E and the central part is a unique mixture based on butyl elastomer, which has the particularities of having good impermeability.
- the central part 51 of the sealing part is separated from the lateral parts 50 by cutting by means of a appropriate tool.
- the lateral parts 50 remaining on the tire, said tire, as shown in FIG. 2 after cutting the sealing part and removing the central part 51, may, after repair or other manipulation, be reassembled easily on a rim of the same type with an independent air chamber and without the central part 51, and be reused under normal conditions of safety and efficiency.
- FIG. 3 shows a partial cross-section of another variant of an assembly according to the invention, comprising a tire P 'of dimension 11.00 R 20 and a sealing piece E', mounted and inflated on a service rim J .
- the tire comprises a carcass reinforcement, the radial one anchored in each bead to a bead 2 ', 2 ".
- This tire P has a diameter measured under the bead and under the bead 2' greater by 6 mm compared to the corresponding diameter of its mounting rim
- the tire is made integral with a sealing part E 'of generally cylindrical geometry formed by a central part 51' extended axially by lateral parts comprising a part 50 'intended to be in contact with the seat of the bead, this part 50 ′ itself being extended axially and radially outward by a flange 53 ′ rising along the vertical external wall of the bead, each lateral part having a thickness equal to 3 mm.
- the central part 51 ′ is made of a mixture based on butyl elastomer and has an average thickness of 3 mm, which has the particularities of having a good i mpermeability and not having a very large baking tack on the other mixtures while the lateral parts are formed from a rubber mixture commonly used for the protective layer of tire beads.
- the junction 80 'between the lateral parts 50' and the central part 51 ' is, seen in meridian section, an oblique junction making an angle ⁇ with the axis of rotation substantially equal to 45 °, said junction being substantially in the extension of the internal wall 40 'of the bead.
- This junction 80 is made visible either by the fact that the rubbers of the three parts of the part E are of different colors, or by the fact that said junction is materialized by a thin layer of color.
- the use of butyl-based mixture for the central part facilitates the separation according to the interface between said central part and the lateral parts by simple pulling of the more or less tapered parts of said central part.
- the service rim J 'on which the assembly described is mounted comprises a first part 61' axially limited by a first hook R 'integral with this part 61' and, mounted removably to allow the assembly and disassembly of said assembly, a second hook 63 ′ locked on the first part 61 ′ by a locking element 62 ′ of which a part of the external radial surface constitutes a seat for the assembly.
- the axial width between the beads of the unassembled assembly is less than the axial width L 'between the rim flanges R' and 63 'and the central part 51' is elastic and deformable in the axial direction under the action of the inflation pressure in order to achieve a good mounting of the assembly on the rim and a good contact of the vertical external walls 440 ′, 440 ′′ of the beads against the flanged edges.
- valve stem 70 ' In addition and to allow the inflation of the assembled assembly, there is an inflation valve removably attached by means of a valve stem 70 'to a valve base 55', itself fixedly attached to a enlarged portion 54 'of the central part of the sealing part 51'.
- This valve stem 70 ' is intended to pass through a window 60' passing through the rim tape 610 ', visible in FIG. 3, closed axially at its two ends.
- the valve base 55 'to be mounted on the central part 51' so that the radially internal end of the means for fixing the valve stem to said base is entirely located within the thickness of said central part.
- these fixing means are located entirely inside a housing 52 ′ formed on the sealing part E and opening on the face radially inside said part.
- the valve stem can be fixed on the base before even performing said mounting as soon as the central part 51 'is sufficiently deformable in an elastic manner to allow the introduction of the valve stem 70' in the window 60.
- the assembly is threaded onto its service rim devoid of its removable rim 63 'and the locking elements 62', the valve stem sliding on the rim strip 610 'before passing into the window 60'; the assembly operation is then continued until complete installation on the rim tape and installation of the removable rim 63 ′ and then by the inflation of the assembly in order to place said assembly against the seats and the rim flanges.
- the central part is reinforced circumferentially to reduce or even prevent it from being deformed permanently inside the window 60 'and then interfere with disassembly.
- the reinforcements 57 ′ in the form of cables or wires, can, in particular but not exclusively, be oriented at a small angle of 0 ° to 5 ° relative to the circumferential direction; these same reinforcements, limited to the central part, can extend to the junction 80 ′ and can serve as a guide for the cutting tool used to separate the central part from the side parts; preferably the angle of the reinforcements is at most equal to 45 °
- a reinforcement solution shown with the embodiment of FIG. 3, consists in incorporating into the central part a reinforcement 56 ′ of generally cylindrical shape with an axis substantially perpendicular to said inner face of material resistant to compression resting on the bottom rim 610 'on either side of the window 60' in the circumferential direction; this cylinder 56 'open on the radially internal face of the central part 51' opposes the deformation of said part inside the window while keeping the valve base far enough away from the jetting bottom.
- the assemblies can be provided with safety means intended to prevent an assembly according to the invention from being able to be inflated beyond a limit pressure when said assembly is not mounted on a rim .
- the invention is not limited to the examples described and shown and various modifications can be made thereto without departing from its scope.
